What 180.352B means in plain language
FMCSR 180.352B governs the retest date marking requirements for rigid intermediate bulk containers (IBCs). An IBC is a reusable transport container designed to hold hazardous materials, and rigid versions maintain their shape whether full or empty.
The regulation requires that rigid IBCs display a clearly marked retest date. This date indicates when the container must be retested to ensure it remains safe for carrying hazardous cargo. The marking must be legible and permanently affixed to the container so that inspectors and handlers can quickly verify that the IBC has current certification. Failure to display this marking—or displaying an outdated or illegible marking—constitutes a violation of this code.
This requirement exists because IBCs degrade over time. Regular retesting catches structural damage, seal failures, and material degradation before a leaking container causes contamination or harm.
What our enforcement data actually shows
Across our 13 million+ inspection records, 180.352B is rarely cited. We have recorded 2 all-time citations for this code, with 1 citation in the last 90 days and 2 in the last 12 months. This places 180.352B at rank #2651 out of 3,036 FMCSR codes by citation volume.
Most importantly for your case: the out-of-service rate for 180.352B is 0.0%. Neither of the 2 cited instances resulted in an out-of-service order. For context, the all-FMCSR average out-of-service rate is 31.4%, meaning this violation is treated as a deficiency to correct but not as an immediate threat to road safety in the way more serious hazmat violations are.
The low citation volume and zero OOS rate suggest that most carriers maintain accurate retest markings on their rigid IBCs, and that enforcement focus on this specific code is minimal compared to higher-risk hazmat violations.
Who gets cited most
Our inspection records show this code cited in Texas, with 1 citation logged in the last 180 days and a 0.0% out-of-service rate in that state.
By carrier, our data shows fleets such as EPBB INVESTMENT HOLDINGS LP (USDOT 1844515) and K EXPRESS INC (USDOT 2439624) each with 1 citation. These occurrences represent isolated events in our database and do not indicate systematic non-compliance.

How severe is this compared to similar codes
180.352B sits in the Hazardous Materials category alongside several codes that carry far higher citation and out-of-service rates:
- 177.834A-HMC (General loading/unloading hazmat) has 3,954 citations with a 99.2% out-of-service rate—meaning nearly all cited carriers were taken out of service immediately.
- 177.817(a) (Placarding violation) accounts for 2,274 citations with a 75.1% out-of-service rate, reflecting the critical safety role of proper hazmat placarding.
- 172.516(c)(6) (Placard damaged, deteriorated, or obscured) has 1,796 citations but only a 1.6% out-of-service rate, comparable to 180.352B's zero rate.
Your 180.352B violation sits at the milder end of the hazmat enforcement spectrum. Comparable codes like 172.602(c)(1) (Emergency Response information maintenance) also show a 0.0% out-of-service rate, indicating that administrative marking and documentation deficiencies are treated as correctable issues rather than immediate safety threats.
How to avoid it
The most straightforward prevention steps focus on IBC inspection and record-keeping:
- Before loading any hazmat shipment, visually inspect every rigid IBC you are transporting. Look for the retest date marking on the container surface. If you cannot clearly read a date, do not load that container. Report it to your carrier's hazmat coordinator immediately.
- Verify the retest date is current. Cross-reference the marked date against today's date. Many carriers maintain a simple spreadsheet or digital log of container retest schedules. Know your fleet's IBC rotation schedule.
- Check for degraded or missing markings during pre-trip inspection. Environmental exposure, abrasion, or fading can obscure the retest date. If the marking is illegible, the container should be taken out of service and re-marked before use.
- Communicate with your dispatcher about container rotation. Ensure that expired containers are replaced before they reach the dock. A five-minute conversation at the start of a shift can prevent a citation.
- Note co-occurring deficiencies. Our inspection data shows that when 180.352B violations occur, they sometimes appear alongside code 173.24F1 (Closures for packagings must not be open or leaking). This suggests that container integrity issues often cluster. If you find a retest marking problem, inspect closures and seals carefully as well.
This code is straightforward: mark the retest date clearly and legibly, verify it is current before transport, and replace containers that have passed their retest deadline. The zero out-of-service rate confirms that inspectors and regulators treat this violation as easily correctable during the inspection process.
